5. The Night Sky • Tuesday, October 21 • A challenge observation: as dawn brightens on Wednesday morning the 22nd, binoculars or a telescope may already show Mercury below the thin crescent Moon very low in the east, as shown here. Look about a half hour before sunrise. • Mercury is not only low but faint: a tiny crescent only magnitude 2.1. If you succeed, this may be the thinnest you ever see Mercury as a crescent: about 10% sunlit. • Wednesday, October 22 • Jupiter's moon Io fades away into eclipse by Jupiter's shadow around 2:43 a.m. Thursday morning EDT (11:43 p.m. Wednesday evening PDT). A small telescope is all you need to watch. Io is the satellite just west of the planet at the time. • Thursday, October 23 • A partial eclipse of the Sun happens this afternoon for most of North America. Seen from the eastern half of the continent, the Sun sets while the partial eclipse is still in progress. Westerners get to see the whole thing. Eastern New England misses out. • While we're at it, here's a preview of the great total solar eclipse that will cross the United States diagonally in less than three years: Americans Will See Total Solar Eclipse in 2017. • Friday, October 24 • As the stars come out this week, Deneb is nearly straight overhead for skywatchers at mid-northern latitudes. Brighter Vega is west of the zenith. Altair is slightly farther from the zenith toward the south. Sky & Telescope
